Why is the sugarcane industry
important to Louisiana?
Of the domestic sugar industries, Louisiana
has the oldest and most historic. Sugarcane
arrived in Louisiana with the Jesuit priests
in 1751 and, in 1795, Etienne deBore
granulated sugar on a commercial scale at
Audubon Park in New Orleans. The Louisi-
ana sugarcane industry is in its third century
of existence, having celebrated its 200th
year of continuous sugar production in
1995.

Sugarcane is produced on more than 450,000 acres of
land in 25 of the 64 Louisiana parishes. In 1999, total
production of 15,982,000 tons of sugarcane yielded
1,675,000 tons of sugar. Growers averaged 37 tons of
sugarcane and 7,800 pounds of sugar per acre, both
new state records. The value of this sugar to farmers,
factories and landlords exceeded $740 million, al-
though the direct economic value generated from the       What are the benefits of burning

                                                            A prescribed burn can be defined as a controlled

The ability of farmers to burn sugarcane is a signifi-
cant economic factor for the survival of the individual
farmer and the sugarcane industry. The sugarcane
plant consists of about 75 percent to 80 percent net
cane (stalks) from which the juice is extracted and the
sugar crystalized. The other 20 percent to 25 percent
of the plant consists of leafy material, including tops,
from which little or no sugar is produced. This leafy
material is called trash. Burning sugarcane before
harvest removes from one-half to two-thirds of this
trash that would otherwise contribute nothing to sugar           Burned standing cane.
production. Further, it is estimated that, by not burning
this trash, the industry would spend more than $24
million in transportation and processing costs. Re-
search data show that there is an actual reduction of 3
pounds in the yield of recoverable sugar per gross ton
of sugarcane for each 1 percent of trash processed by
the factory. There is currently no profitable or effec-
tive way to deal with this large volume of trash by
mechanical means.

Until proven technology allows economically efficient
harvesting without burning, it is critical that growers          Burned standing cane being harvested

smoke and ash management. Louisiana is not the only
state, nor is sugar production the only industry, facing
this challenge. Every industry that uses prescribed
burning recognizes that a cost-effective mechanism for
reducing or eliminating open field burning is a re-
search topic of high importance. Further, because of
current low domestic sugar prices, the farmer would be
hard pressed to survive without burning to reduce
production costs and improve quality of the product
delivered to the factory for processing.

The CPBM will provide education and training to all
of their employees who help to conduct burning
operations. Further, the CPBM should ensure that all
individuals who conduct prescribed burns are trained
and certified. A thorough explanation of the goals and
recommendations will help employees understand the
importance of smoke and ash management. Addition-
ally, it should be emphasized that prescribed burns                   Prepared by: Ben Legendre, Extension Specialist
